Embodiment Construction
[0023] The present invention will be described in detail below in conjunction with specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all belong to the protection scope of the present invention.
[0024] Such as figure 1 As shown, a kind of surface chemical milling protective glue automatic spraying device of melon petal type parts provided by the present invention comprises: spraying robot arm 3, is used for carrying out automatic spraying; The position slides; the positioning track 5 is used to define and fix the specific position of the glue spraying frame car 7; the electrical control system 1 is used to control the overall operation of the spraying robot arm 3 and the high-pressure airless s...

The invention provides a method and device for automatically spraying chemical milling protection glue on surfaces of melon-section-type parts. The device comprises a portal frame travelling shaft 2,a spraying robot arm 3, a high-pressure airless sprayer 4, an electrical control system 1 and a rack car 7; the spraying robot arm 3 is movably connected to the portal frame travelling shaft 2; the output end of the high-pressure airless sprayer 4 is arranged on the spraying robot arm 3; the electrical control system 1 is electrically connected with the spraying robot arm 3 and the high-pressure airless sprayer 4 to control the spraying robot arm 3 and the high-pressure airless sprayer 4 to operate; and the rack car 7 is used for loading the melon-section-type parts. The protection glue is automatically supplied through the high-pressure airless sprayer, meanwhile, manual spraying operation is replaced with the robot arm, thus the spraying quality and efficiency of the chemical milling protection glue are greatly improved, the labor intensity of the melon-section-type large structural parts is effectively lowered, and the operation environment is effectively improved.
Description
technical field [0001] The invention relates to the field of spraying devices, in particular to an automatic spraying method and device for chemical milling protective glue on the surface of melon petal parts. Background technique [0002] At present, the machining accuracy and technology of CNC machine tools for melon petal parts cannot meet the design requirements, so that the melon petal aluminum alloy parts in the domestic and foreign aerospace fields are still processed by chemical milling. First, the aluminum alloy The surface is sprayed with protective glue, then engraved with protective glue, and finally chemical milling. For example, the patent document CN105483704A discloses a deep chemical milling method for large structural parts of TA12 and TA15 titanium alloys. [0003] Due to the high viscosity and long curing time of chemical milling protective glue, manual spraying is basically used at home and abroad at present, and no other automatic spraying process has ...
